When GPS is used for air-borne application the
coordinates of all the required airports and the relevant
information about the airport has to be loaded on to the GPS. This
information is available in the CD containing the Jeppeson database.
The software 'Jeppeson database loader' contains a menu driven GUI
that will help the user to select and down load the relevant
information on to the GPS before the aircraft takes-off. As this
software is PC based one, the database could be loaded even on-board
the aircraft using a laptop computer.
